every particle of moisture from the 
cavity, thus preventing further de- 
c;iy. Thirdly, should the cavity be 
so large as to require bracing, iron 
braces, trusses or other mechani- 
cal means are jesorted to. This 
adds physical strength to the tree. 
Fourthly, the cavity is filled with 
cement, put in in sections, each 
division or section forming a ball- 
and-socket joint, allowing, for the 
swaying of the tree, which is an- 
other patented device. By thus 
filling and bracing the limbs of 
trees it is remarkable how even

ancient trees or others of much 
value can be saved, and their ex- 
istence perpetuated for many 
generations longer. The cement 
work may even be completely 
covered by the bark in the course 
of time. 
Trees, Transplanting. — 
The great merit of trees from a 
nursery lies in their fine fibrous 
root sysfjem. Care is always exer- 
cised by the nurserymen in this 
respect, the trees or shrubs be- 
ing lifted every two or three 
years, in order to prevent the 
development of long, sappy roots, 
and to ensure a mass of fibrous 
roots. Plants brought in from 
the wild often fail because of 
their poor root system. Such a 
tree as the one illustrated on 
this page has every chance to 
succeed. 
Tussock Moth. — The cater- 
pillar of this moth is of a gen- 
eral gray color with its back or- 
namented with a series of four 
tufts of white hair. The head 
is bright red in color and has 
two pencils of black hair extend- 
ing forward, whil^ a single simi- 
lar pencil extends back from 
the end of the body. The very 
best way of fighting this vo- 
racious leaf eater is by collect- 
ing the egg masses.
